![]() ![]() ![]() To check the battery voltage, a check position is provided on the measuring range shutter. The battery is switched on with the rotary switch (which also represents the R, C adjustment knob at the same time). The working range of the electronics is between 4V and 7V. The electronic components of the meter are powered by four 1.5V batteries and take a current of about 2.5mA. ![]() The large measuring range and the high accuracy of 1% at AC and DC, allows universal use in the radio and television service in test field and laboratories. The field effect transistor chopper for DC measurements and the multiple negative feedback guarantee high stability and negligible drift. The high sensitivity is achieved by means of a battery-powered transistor amplifier. It was specially developed for measurements in the field of electronics and for all those applications where practically no power is required. The electronic instrument Unigor 6e combines the advantages of classical measuring technology with those of modern electronics. In this case, it is the model Unigor_6e from the 70s.Īn excerpt from the preface of the operating manual: The power supply of the multimeter takes over a 1.5V mono cell.Ī good friend of the older generation of technicians is certainly the analog multimeter of the manufacturer Unigor. Like the Unigor 6e, the 3n model is also equipped with various safety features. The measuring accuracy is 1% for DC and 1.5% for AC measuring ranges. The voltage drop in current measurements is given as 12mV in the 120uA range and 120mV in the 30A range. The internal resistance for voltage measurements is a maximum of 4MOhm in the highest measuring range (see photo technical data). The measuring mechanism is a “clamping band measuring unit” with a very good vibration resistance and low self-consumption. All measurements (except the 10A range) are possible on just one terminal pair. The measuring mode and polarity reversal is realized with a push-button switch. It was characterized by the large measuring range of 52 measuring ranges, all of which can be selected with just one selector switch. From the years from 1964 comes the analogue multimeter Unigor 3n from Norma, respectively Goerz-Metrawatt. ![]()
